I have 30 years of experience in the fields of chemistry, corrosion science and engineering, failure analysis, energy conversion, fuel cells and batteries with specific knowledge of stress corrosion cracking, corrosion fatigue, pitting corrosion, general corrosion, corrosion mitigation and inhibition, technical due diligence and forensic materials science. I have published on such topics as corrosion science and engineering, energy conversion and prediction of damage. I have testified 20 times on topics such as corrosion failures, determination of headlight activation and steam turbine failures.
